Question

Mg+HCl---> Al+H2SO4---> Na+H3PO4---> Zn+H2SO4---> Fe+HCl---> Ca+H2SO4---> Cu--->CuO--->Ca CuO--->CuCl2--->Cu(OH)2--->CuO

Answer 1

Я зделала второе
cu+o2=cuo
cuo+h2=cu+h2o
cuo+hcl=cucl2+h2o
cucl +h2o=cu(oh)2
cu(oh)2=(нагревание) cuo+h2o

Answer 2

Mg+2HCl=MgCl2+H2
2Al+3H2SO4=Al2(SO4)3+3H2
6Na+2H3PO4=2Na3PO4+3H2
Zn+H2SO4=ZnSO4+H2
2Fe+6HCl=2FeCl3+3H2
Ca+H2SO4=CaSO4+H2

Cu=CuO=Ca
2Cu+O2=2CuO
Третье не знаю

СuO=CuCl2=Cu(OH)2=CuO
CuO+2HCl=CuCl2+H2O
CuCl2+H2O=Cu(OH)2+Cl2
Cu(OH)2=(t)CuO+H2

Answer 3

The series of reactions you provided can be broken down as follows:

1. Mg + HCl → (Magnesium reacts with Hydrochloric acid) No reaction Magnesium does not react with hydrochloric acid.

2. Al + H2SO4 → (Aluminum reacts with Sulfuric acid) Al2(SO4)3 + H2 Aluminum reacts with sulfuric acid to produce aluminum sulfate (Al2(SO4)3) and hydrogen gas (H2).

3. Na + H3PO4 → (Sodium reacts with Phosphoric acid) Na3PO4 + H2 Sodium reacts with phosphoric acid to produce sodium phosphate (Na3PO4) and hydrogen gas (H2).

4. Zn + H2SO4 → (Zinc reacts with Sulfuric acid) ZnSO4 + H2 Zinc reacts with sulfuric acid to produce zinc sulfate (ZnSO4) and hydrogen gas (H2).

5. Fe + HCl → (Iron reacts with Hydrochloric acid) FeCl2 + H2 Iron reacts with hydrochloric acid to produce iron(II) chloride (FeCl2) and hydrogen gas (H2).

6. Ca + H2SO4 → (Calcium reacts with Sulfuric acid) CaSO4 + H2 Calcium reacts with sulfuric acid to produce calcium sulfate (CaSO4) and hydrogen gas (H2).

7. Cu → (Copper by itself) Copper does not react with anything in this case.

8. CuO → (Copper(II) oxide) Copper(II) oxide is a compound and does not undergo any reaction by itself in this sequence.

9. Ca CuO → (Calcium reacts with Copper(II) oxide) CaO + Cu Calcium reacts with copper(II) oxide to produce calcium oxide (CaO) and copper metal (Cu).

10. CuO → (Copper(II) oxide) Copper(II) oxide is a compound and does not undergo any reaction by itself in this sequence.

11. CuO + CuCl2 → (Copper(II) oxide reacts with Copper(II) chloride) 2CuCl + O2 Copper(II) oxide reacts with copper(II) chloride to produce copper(I) chloride (CuCl) and oxygen gas (O2).

12. CuCl2 + Cu(OH)2 → (Copper(II) chloride reacts with Copper(II) hydroxide) 2Cu(OH)Cl Copper(II) chloride reacts with copper(II) hydroxide to produce copper(II) hydroxychloride (Cu(OH)Cl).

13. CuO → (Copper(II) oxide) Copper(II) oxide is a compound and does not undergo any reaction by itself in this sequence.

Please note that these reactions are simplified representations and may not account for specific reaction conditions or stoichiometry. Additionally, it's important to handle and conduct chemical reactions safely in a controlled laboratory environment.
